start by adding 2 to both sides to get 3r^2 = 48. then divide both sides by 3 to get r^2 = 16. square root both sides to get r = 4.
mayeke
3r^2 – 2 = 46

• Add 2 on both side; 3r^2 = 48

• Remove the square from 3r by putting the square root of 48 = 6.9 hence:
3r = 6.9

• divide both sides by 3; 3r/3 = 6.9/3
r = 2.3
